  Disables the sending of a PORT command to the remote server.

  By default, the FTP client attempts to use a PORT command when
  establishing a connection for each data transfer.  If the PORT
  command fails, FTP will use the default data port.  Disabling
  the PORT command is useful in communicating with certain FTP
  implementations which ignore PORT commands.

  This option is enabled by default.
